Just fixed it, all it took in the end was removing the breach then putting it back on square.I think I must have knocked it or something when I was mucking around with the clipping issue the other day as the gun has just gotten a fair bit quieter, it got a lot louder the other day when I drilled the hole in the end of my LDC out another mm, I thought the increased sound was from that

Now to have another go at sighting it in as soon as this wind dies down!

I had accuracy issues with my Disco, changing POI, etc. Before tearing it down I was on the phone to Crossman explaining that I thought it had a bad crown. In retrospect, I remembered when I first got it and removed the front sight, the barrel end was not square (as the barrel end has a flat area that the grub screw contacts through the front sight), and was cocked to the side. I didn't think much on it at the time not being familiar yet with my Disco and the posts I made never got to the root of the problem I was experiencing which is why I changed the barrel. When I reassembled the breach and barrel I was extra careful to make sure the transfer port and barrel matched up square and flush. Whoever assembled the gun at the factory failed to mate the transfer port to the barrel properly and I suspect, when there was a rash of complaints on the forum regarding the Discovery poi issues, that it may have been as simple as a shoddy factory assembly. Many of you will remember back in the early summer that the darkside had this issue going on for almost a month with newly bought Disco's from several members. The overall consensus was "bad crown", bad barrel although I do remember MustangMike mentioning transfer port alignment. Glad you posted this thread Shiloh; it jogged my brain and the solution I sought but couldn't find was there all along.
